Application ined october 1o, 1922,- seriai No. 593,59a` Renewed Maren 1,1997;

This invention relates to a hoist attach# ment for tractors, and moreparticularly tov suchy an attachment designed to be attached to thefront of a tractor,- driv'en from the belt pulley shaft thereof, andcontrolledby the operative from a point at one side ot the front end ofthe tractor; A

It has for,r its objecty the "provisionof a Winch or hoist attachmentfor a tractor to be carried upon the front end thereof, and drivenl Withpower fromV the tractor" engine through the belt pulleyshaft andcontrolled by an operative. from the tractor seat or from apposition atVthe front of the tractor. A further object is the`r production of anovel means for mounting' the attachment upon the tractor and one'l inwhich the strains placed upon the Winch orhoist will' be borne byportions off-the tractor capable di? sustaining' them. A further' objectis the productionot a simple mounting for such a Wincl-r or hoistattachment upon the frame- Work of the radiator o-f the tractor.`

@ther objects and advantages of thoriuvention Will' hereinafter appeariin the fol lowing description, and the novel features thereof' will beparticularly' pointed out in n thereto 5f the appended claims;k

My' inventione is susceptible? ofV al number of.l embodiments;y thatshownz and described in this specification' is one of them' which hasbeen found practicable in construction and operation. It must, however,be taken as indicative of the invention only.

Y ori vhoist upon the. tractor front end, there are provided abailr 10and stirrups' 1.1. For controlling the movement of the Winch, there' isprovided an' extension clutch control, shown more particularly ligiuresA1, 4, and: 5:. "lheseik parts' will now be described; and theirindividuali functions pointed out, after which a recital of theirconjoint use will be given.=

Referring to: Figure 6;, the framework of my Winch attachment comprisesycrossrail's 12i and 13 connectedl f vertical rails 14 and 115, all ofangle'ffironso suitable size.y At the ends of the crossl rails are,arched bearing supporting' members 16-y and 17 suitalivlyr braced by thestraps 18; and 19'.4 Y

Iii the. bearings 2Q may be mounteda drive shaft 21, and in the:vapertured ears 22: may' loel mounted a shift rod 23,v while intheebearings 24 may befmountedthefwvndiing,` drunr shaft 25.l All otthese parts are somewhatA similar to: these same elements deL scribed inPaten-ti Number 1,557,5170 dated October 13,` 19215, issued on' myf`copending application` Seriali Number 518,980, ,filed Nove'mberl 301921, and a more detailed' descrip*- tion therejo. need not be gifvenMin this specificationf.. y

Upon the' end: of` the shaft 21, there is mounted a1 sprocket 26;` whichis driven through the clra'irr 27 from the drive sprocket28 upon theend'. of the beltfpulley shaft, with vvhich'dt'k is1cust-omary to equiptractors ofthis generafl type. kllt willbe understood that this beltpulley shaft is driven` from the enginey of the* tractor'y as long, asthe en gine isirunning and when the tractor clutch pedal 29 is innormalor` engaged? condition. Power received'ifroni the beltfpulley shaft 30will be transmitted through,` sprocket 26, shaft 21, and sliding inion31 to gear `32 upon the end1y of ther rum 38. It Willbe 4appreciatedthat the lever 34 and*` yoke 35 Referring now more particularly toFigurel 3, it will be seen that thel vertical: angle members 14 and 15are spaced apart justa sufficient distance to lie upon either side ofthe framework 36 of theradiator of the tractor and that the cross railsk12 and 13 will lie against the face ofy said radiator framework, asshown in Figure 1. The vertical members 14, and carry a baill 10 formedof a single piece of iron stock of sufficient strength. This bailcomprising an arched portion conforming tothe contour of the uppersurface of the tractor water tank 38, engages the same beyond'the mouth39 into which water is poured in lling the tractor radiator. v

The leg'portions of this bail terminate in bent ends which arescrewthreaded to receive nuts 40 and 41, the said bent ends being passedthrough the angle members 14` and l5. It will be appreciated that thisbail in` conjunction with the outstanding flanges i of the angle members14and 15 will-supfrom the radiator.

Cil

port a winch framework ragainst the face of the radiator. However inthe. operation of the winch a pull or strain upon the frame would causethe winch to be pulled away In order thatfthe winch may be held undersuch strain firmly against the radiator, and the strain placedupon partsof the tractor strong enough to bear them, I have provided stirrups 11,11, which extend rearwardly and pass around the axle housing of thetractor. The legs of these stirrups are slightly bent at their lforwardends and screwthreaded. These'ends Vpass through apertures in themembers 14 and 15 and the cross rails 12 and 13, constituting the meansfor connecting these elements of the fwinch framework togethen Suitablenuts 42, and 43 are provided to'produce a clamping engagement ofthe'parts. It will be appreciated that by the use off'the stirrups 11,11, the winch attachment is clamped against the edges of the radiatorframework and that any pulling strain 'placed upon the drum istransmitted to the axlev housing which is of sufficient strength astobear it.

I have selected for the purpose of illustration as the means for drivingthe winch from the power plant of the tractor a small sprocket 28mounted upon theend ofthe belt pulley shaft 30 and the drive sprocket 26fixed upon the drive shaft 23 Lof 'the hoist attachment connected bymeans of the chain 27. It is obvious, however, that other means may beemployed to accomplish this result. For the purpose of controlling themovements of the winch, I have provided a brake drum 44 upon one end of.thespool actuated by the lever 45 (more fully described in my patentnumbered 1,413,421, April 18, 1922) and in addition the extension clutchcontrol'similar in many krespects to that set forth inf my patentnumbered 1,418,265, May 30, 1922.

Lerares 'This extension clutch control n comprises a `rod 46 journalledat one end 47- in the frame work of the Winch and providedthere with thehandle 48`a'nd at its opposite end in Referring to Figures 4 andy5,-rvit will seen that the bearing 49 is formed upon the end ofastrap', Whose body 54is curved and attached to Ithe tractor by means ofthe machiney screws 55 Which hold theJ belt pulley shaft housing ,to thetractor.As shown in Figure 5, the upper. endv of the strap 'is bentLawayrfrom ythetractor body so that the. crank end 50 may 'be-rotated inthe depression of the clutch `pedal beyond a deadcenter, coming intovcontact with v the tractor body, when it `will be automaticallyheldwith the clutch in releasedv position.

`In assemblingthe parts of my hoist attachment,rit willbe-appreciated-that the l relative. position of ythe parts of the winchis the reverseof those disclosedin'my prior application for patent, so`that the controls will all beupon the .side of the machine havingthe/,belt Qpulley. t `For this'purpose no change in design of -the winchparts is necessary with the exception-'of the vertical rails 14 and 15.which are spaced further apart. `The frame-of the winch attachment `isthen equipped with the bail or saddle 10.

It maybe placed intoja position onvthe :tractor wherethe bail orsaddle`can be en'- gaged over the mouth 39y and the vertical lou rails` placedto` either side of. the radiator.

In this position it will be seen that `the attachment is held suspendeduponthe tractor.

y The stirrups or stay rodsrll are now made to straddle the tWo ends ofthe axle housing andthe legs thereof are attached to' the winch frame inthe 'manner' described. This will cause the Winch frame to be yclampedto the radiator frame, and will have the effect yof `placing the pullingstrain of the winch while in operation upon the` axle housing, .x`

which isdesigned tov bear heavyv strains.

While I have shown and describedr the n stirrups or stay bolts asconnectingjthe cross ticular, and one which will place the strains Wherethey inayy be born with ease.

Having described my invention, what I claim as new, and desire to secureby Letters Patent isy l. In combination with a tractor Whose body ismade up of sections including a rear axle housing, of a framecarryingactive Winch elements mountedr on the front of said tractor, means forholding said frame against vertical movement, and a rod bent to encirclethe axle housing of thei tractor and having its ends attached to saidWinch frame.

2. In a Winch attachment for tractors, a frame carrying activeWinch'elements, a bail or saddle for suspending said Winch frame fromthe frontend of said tractor, and stirrups extending from said Winchframe and passing around the axle housings at the rear of said tractorfor holding said Winch frame` to the front end of said tractor andtransmitting the strains on said Winch elements to the body of thetractor. y

3. In a Winch attachment for tractors, a frame carrying active Winchelements adapted to be attached to the front end of said tractor, andcomprising cross rails and vertical rails, said vertical rails havingflanges adapted to straddle the front end of the tractor, a bail orsaddle carried by said vertical rails Vtor suspending the frame from thetractor, and stirrups or stayrods extend-- ing from said vertical railsto the rear axle housing to brace said winch 'frame against said tractorfront end and bear the strains of said Winch operation.

In testimony whereof I affix my signature.
